Mex - I vaguely remember you mentioning unreliable AC power. My experience with PD converters is that they need a good 120 volt or higher sine wave to achieve their rated output. So if you don't have that and want, say 60 amps, I'd recommend going to the 80 amp converter. Just the opposite, the wfco converters I've had will supply their rated current at 14.4 volts with marginal power. I can't be more specific other than it can be below 120 volts and/or have a crappy waveform. The wfco power section with the pd's push button would be a nice combination, somewhat analogous to the thinking that an ideal pickup would be a Ford body, Dodge engine, and GM Allison transmission.
For a kWh meter, I'm assuming you mean on the DC end. A battery monitor would of course be nice. How about this for a lower cost alternative?

There was a post a few years ago on how to accomplish that with a 91xx series converter, substituting a homebrew circuit for the charge wizard.
